Choosing the Right Book Publishing Services?

I've recently finished my manuscript and started exploring my options for getting it published. The number of book publishing services out there is overwhelming—traditional publishers, hybrid publishers, self-publishing platforms, and more. I'm leaning toward a hybrid model because I want some creative control but also professional help with editing, cover design, and distribution.
Has anyone here worked with hybrid book publishing services? Are there any red flags I should look out for or specific companies you'd recommend avoiding? I'm especially concerned about contracts that take away too many rights or unexpected costs down the line.
I’d love to hear your experiences—good or bad—about the publishing path you chose. What made you feel confident about a certain service? Were there any hidden gems or well-known names that truly delivered? Let’s help each other make smarter choices and avoid common pitfalls!
